'r MULTIJET connnnsnn.

Application filed March 8, 1923. Serial No. 628,598.

To all whom it may concern: I

Be it known that 1, PAUL A. BANonL, a citizen of the United States, anda resident of ,Nutley, county of Essex, and State of or New Jersey, haveinvented a certain Twin Multijet Condenser, of which the following is aspecification, accompanied by drawings. This invention relates to twinlow level multi-jet condensers, but more partlcularly to balancing meansconnected between the twin condenser bodies.

By connecting a balancing pipe between the ejectors one condenser can bestarted in operation while the other condenser is running and the vacuumbreaker on the condenser which is startin will be prevented fromblowing, because t e surplus water is drawn out of the throat of thecondenser which is running and ejected to atmosphere. By drawing some ofthe water out through the balancing pipe from the condenser which isstarted, that condenser may continue to receive water, as the valve onthe supply for.

that condenser is opened and in this way sufiicient velocity is built upto cause the condenser'to operate in the normal way.

The advantages of my balancing pipe construction, in addition to thosestated, reside in the fact that one condenser can be readily andconveniently shut down when 'not required, as for instance in coldWeather when only one condenser is necessary to hold the same vacuumwith cold water; and since all light loads can be carried on onecondenser, and when the peak load comes, the other 7 condenser can bethrown into operation; the complete outfit is more'flexible, becausethere is in efi'ect two complete units having two supply pumps, and ione unit breaks down or goes out of service for any reason, operationcan still be carried on with the other unit; and as a further advantagethe balanc-, ing pipe itself affords a means for draining one condenserfor starting operation.

The invention is illustrated in the accompanying drawing, which is alongitudinal sectional elevation of a twin low level multijet condenser,artly in diagrammatic form, without such details as are not necessary tothe understanding of the invention.

Referring to the drawings, the twin condenser comprises the substantiallcircular up-right condenser bodies, A and havmg the usual difiusers orejectors C and D, and

denser.

tail pieces E and F, which tail pieces are submerged below the waterlevel G in the sum or tank H having the wier J and outlet Q. The tailpieces as shown are provided with the counter-weighted flap valves L andO and as shown, the valve L is open since the condenser A is in fulloperatlon and the valve 0 is closed since the condenser 4 B is startingto operate. In the present instance, a common unitary connecting steamand water inlet head P extends over, both the condenser bodiesv A and B,as shown in my co-pending application, Serial No. 623,599 filed arch 8,1923, and this head is provided with theopenin in its lower end adaptedtobe fitted to the condenser bodies respectively. The upper opening ofthe common head is adapted to be fitted to a casing Q which may 1% thecasing of a turbine or other prime mover from which the steam issupplied to the con- The connecting head P connects the twin condenserbodies to each other and also connects them with the turbine casing. Thehead P is provided with the water inlets 1t and S for the condensers Aand B respectively and in accordance with my construction each inlet isassumed to be supplied with water from a separate supply pump (notshown). The water passes to the nozzle plates 'l and U having thenozzles V and W formin multi-jets directed towards the throats and Y ofthe condenser bodies A and B res ectively. Each condenser body is alsore erably provided with combining tubes ormed w1th the operating guidevanes Z between which the steam gasses to the jets. The condenser bodiesand'B may each be provided with vacuum breakers, one vacuum breaker abeing shown on the body B of any suitable or standard construction.

The balancing pipe 6 is shown connecting one condenser body with theother and a valve 0 is preferably provided in the pipe vacuum, but noload. In such'case, the.;con-

or blowing because the surplus-water from 5 the condenser B is drawnofl' over to the throat of the condenser A. The condenser B can thuskeep receiving water and sufiicient velocity will be built up to causethe ejector of the condenser to operate in the m normal way.

I claim:

1. A twin low level multi-jet-condenser,

comprising a, pair of up-ri ht condenser casmgs having difiusers, anta1l 1eoes pro- 15 vided with valves, said tail pleces being adapted tobe surmerged, nozzles within the condenser casings for producing waterjets, a balancing pipe connecting one casing with v the other at pointsabove the difi'users, and a valve in. said balancing pipe whereby one'condensermay be started while. the other is 'difi'users providedwith-valves and adapted to be submerged, nozzles within the condensercasings for producmg water ets, a

balancing piping connecting the throat of one condenser casing with thethroat of the other condensercasing at points above the diffusers, and avalve in said balancing pi e whereby one condenser may be started whilethe other is under vacuum and load.

In testimony whereof I have signed this specification.
